여러개의 특허 [즉, 암베르트슨(Amberntsson) 등에게 허여된 1976년 4월 27일자 미합중국 특허 제3,953,862호, 혼(Hon) 등에게 허여된 1977년 5월 24일자 미합중국 특허 제4,025,928호, 카수가자마(Kasugajama)등에게 허여된 1981년 12월 15일자 미합중국 특허 제4,306,245호에 인쇄용 잉크 분사장치가 기재되어 있으며, 인쇄 및 제도에 사용되는 잉크 분사장치의 개략적인 용도는 공지되어 있다. 그러나, 종래의 분사인쇄기 및 그 핵심 부품인 잉크 분사헤드(ink jet head)는 고가이며 구조가 복잡하게 되어 있다. 종래의 잉크 분사헤드가 고가이고 또한 그 구조가 복잡하기 때문에, 선행 특허들의 발명자들은 이 헤드를 수년 동안 연속해서 사용할 수 있고 수만장씩 인쇄할 수 있도록 고안하였으며, 잉크를 재충진시키고, 유지가 필요한 조립체의 여러 부품에 세척 및 수선을 위해 접근할 수 있도록 고안하였다. 자연히, 선행 기술에 있어서 이와 같은 요구 사항은 헤드의 복잡성을 더욱 증가시키고 가격을 상승시켰다. 다른 결점으로는 수많은 사용자가 대개 그러하듯이, 사용자는 잉크 저장기를 다시 충진시키거나 또는 잉크 카트리지(catridge)를 교환해야 하는 번잡한 작업을 수행해야만 된다. 위의 두가지 경우에 있어서, 사용자는 특정형태의 유체 결합 장치 또는 유체 플러그(plug)를 분리하고 다시 연결시켜야 하기 때문에, 양손과 옷이 잉크에 노출되게 된다.Multiple patents [i.e., US Patent No. 3,953,862, issued April 27, 1976 to Amberntsson et al., US Patent No. 4,025,928, issued May 24, 1977 to Hon et al., Kasu An ink jetting apparatus for printing is described in US Pat. No. 4,306,245, filed Dec. 15, 1981 to Kasugajama et al., And a schematic use of the ink jetting apparatus for printing and drawing is known. However, conventional jet printers and ink jet heads, which are core parts thereof, are expensive and complicated in structure. Because the conventional ink jet head is expensive and its structure is complicated, the inventors of the prior patents have designed the head to be able to use it continuously for several years and print tens of thousands of sheets, and to refill the ink and to maintain the assembly. Designed to provide access to several parts for cleaning and repair. Naturally, such requirements in the prior art further increased the complexity of the head and raised the price. Another drawback is that, as many users usually do, the user must perform the cumbersome task of refilling the ink reservoir or replacing the ink cartridge. In both cases, both hands and clothes are exposed to the ink because the user must disconnect and reconnect a particular type of fluid coupling device or fluid plug.

본 발명은 일회용으로 사용할 수 있을만큼 간단하고 염가인 헤드를 마련함으로써 선행 기술의 잉크 분사 헤드에 내재하는 문제점을 해결한다. 본 발명의 헤드는 밀봉된 잉크 저장기, 잉크, 분사장치(즉, 열적 박막 저항기), 전기 연결장치 [즉, 박막 전도성 런(run) 및 패드(pad)], 유체 연결장치, 및 분사 오리피스를 포함하는 완전 자체 내장된 단일 장치로 되어 있다. 밀봉된 저장기내의 잉크를 완전히 사용하는 대체로 500페이지 정도를 인쇄한 후에는, 전체 헤드를 폐기시키고 새로운 헤드로 갈아 끼운다. 따라서, 사용자는 단지 위험성이 없는 낮은 전압으로 연결된 전기적 연결장치 및 기계장치를 분리 및 연결시키기만하면 되며, 유체(즉, 잉크) 결합장치를 만질 필요가 전혀 없게 된다.The present invention solves the problem inherent in the ink jet head of the prior art by providing a head which is simple and inexpensive enough to be used for single use. The head of the present invention comprises a sealed ink reservoir, ink, sprayer (i.e. thermal thin film resistor), electrical connectors (i.e., thin film conductive run and pad), fluidic connectors, and spray orifices. It's a complete, self-contained single device. After printing approximately 500 pages of the ink in the sealed reservoir, the entire head is discarded and replaced with a new head. Thus, the user only needs to disconnect and connect the electrical connections and mechanisms connected to the low voltage without risk, and there is no need to touch the fluid (ie ink) coupling device.

이하 첨부된 도면을 참조로 하여 본 발명을 상술한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 일회용 잉크 분사헤드를 분해하여 도시한 것이다. 유리 또는 세라믹 기층(10)은 다수의 박막열적 분사저항기(20) 및 박막의 금속 전기 연결 런(30) 및 패드(40)를 반송한다. 분사 공급공(50)을 기층(10)을 통해 마련하여, 저장기면(60)으로부터 기층(10)의 분사면(70)까지 잉크가 흐를 수 있도록 한다.1 is an exploded view of the disposable ink jet head. The glass or ceramic base layer 10 carries a plurality of thin film thermal injection resistors 20 and thin film metal electrical connection runs 30 and pads 40. The injection supply hole 50 is provided through the base layer 10 to allow ink to flow from the reservoir surface 60 to the injection surface 70 of the base layer 10.

오리피스 판(80)은 에폭시 접착제 또는 땜납으로 기판(10)에 부착된다. 오리피스 판(80)은 유리, 세라믹, 또는 니켈 등의 금속으로 구성되고, 각각의 분사 저항기(20)에 연관된 다수의 소형(0.0254-0.0762mm) 낙하 배출공(90)을 포함하여, 잉크를 인쇄매체(종이)를 향하여 X방향으로 적절히 분사할 수 있도록 하는 분사 격실 및 오리피스를 마련하게 된다. 오리피스 판(80)에는 또한 기층(10)에 면하는 측면 위에서 홈(95)를 마련하는데, 상기 면은 기층(10)과 결합되어 모세관 작용에 의해 잉크가 분사 공급공(50)으로부터 낙하 배출공(90)으로 유동될 수 있도록 한다. 오리피스 판(80)에는 또한 선적 및 사용중에 분사정항기(20)에 마모 손상 또는 충격 손상이 발생하는 것을 방지하기 위해 기계적인 보호 장치를 마련한다.Orifice plate 80 is attached to substrate 10 with epoxy adhesive or solder. The orifice plate 80 is made of metal, such as glass, ceramic, or nickel, and includes a number of small (0.0254-0.0762 mm) drop ejection holes 90 associated with each injection resistor 20 to print ink. Dispensing compartments and orifices are provided to enable proper spraying in the X direction towards the medium (paper). The orifice plate 80 is also provided with a groove 95 on the side facing the base layer 10, which is combined with the base layer 10 so that ink is dropped from the injection supply hole 50 by capillary action. Allow flow to (90). The orifice plate 80 is also provided with a mechanical protection device to prevent abrasion damage or impact damage to the jetting machine 20 during shipping and use.

기층(10)은 접착제에 의해 플래스틱으로 성형된 지지판(110)내의 요홈(100) 내에 밀봉 장착된다. 지지판(110)은 다음과 같은 목적을 위해 마련한다. (1) 지지판은 기층(10)을 기계적으로 지지한다. (2) 지지판에는 전체 헤드를 인쇄기에 정렬시키기 위해 사용되는 성형된 위치 정렬 핀(120)이 마련된다. (3) 지지판에는 압입 성형된 홈(130) 및 공급공(140)을 마련하는데, 이들은 기층(10)의 저장기면(60)에 결합될 때 모세관 홈을 마련하여 잉크를 분사 공급공(50)으로 공급한다.The base layer 10 is hermetically mounted in the groove 100 in the support plate 110 molded into a plastic by an adhesive. The support plate 110 is provided for the following purposes. (1) The support plate mechanically supports the base layer 10. (2) The support plate is provided with a molded positioning pin 120 which is used to align the entire head to the printer. (3) The support plate is provided with a press-molded groove 130 and a supply hole 140, which are provided with a capillary groove when coupled to the reservoir surface 60 of the base layer 10 to inject the ink into the injection supply hole 50 To supply.

탄성의 중공형 잉크 저장기 (150)은 지지판(110)의 배면(160)에 밀봉식으로 접착 장착된다. 잉크 저장기(150)은 탄성의 가요성 실리콘 고무로 단일체로 제작하거나(도시 안됨), 가요성 탄성 플래스틱 반구체(180)에 대체로 골무형으로 고착된 비교적 비가요성인 플래스틱 반구체(170)으로 형성한다. 전기한 양 경우에 있어서 저장기(150)은 사용시에 공급공(140)을 통해서만 배출되어지는 잉크를 저장할 뿐만 아니라 잉크에 배압을 제공하여 분사 저항기(20)이 작동될 때 잉크가 낙하 배출공(90)을 통해서만 배출되도록 한다.The elastic hollow ink reservoir 150 is sealingly adhesively mounted to the back surface 160 of the support plate 110. Ink reservoir 150 may be made of a single piece of elastic flexible silicone rubber (not shown), or may be a relatively inflexible plastic hemisphere 170 that is rigidly fixed to the flexible elastic plastic hemisphere 180. Form. In both cases, the reservoir 150 not only stores the ink which is discharged through the supply hole 140 in use, but also provides back pressure to the ink so that the ink is discharged when the injection resistor 20 is operated. Only through 90).

다음에 플래스틱으로 성형된 외측 하우징(190)은 지지판(110)의 배면(160)에 접착식으로 정착되어 잉크저장기(150)을 보호하는 강한 기계적 보호부를 형성한다. 잉크가 낙하 배출공(90)을 통해 배출될 때, 잉크 저장기(150) [또는 2개의 부분으로 제작될 경우에는 반구체(180)]은 서서히 수축된다. 따라서, 제2도에 도시한 바와 같이, 외부 하우징(190)을 통과하는 구멍 형태인 공기압균형 환기공(200)을 마련하여 외부 하우징(190)내에 부분적인 진공이 발생하는 것을 방지해야 할 필요성이 있게 된다.The outer housing 190 molded of plastic is then adhesively fixed to the back surface 160 of the support plate 110 to form a strong mechanical protection to protect the ink reservoir 150. When the ink is discharged through the drop discharge hole 90, the ink reservoir 150 (or the hemisphere 180 in the case of two parts) is gradually contracted. Accordingly, as shown in FIG. 2, it is necessary to provide a pneumatically balanced ventilation hole 200 having a hole shape passing through the outer housing 190 to prevent partial vacuum from occurring in the outer housing 190. Will be.

잉크 저장기(150)은 충진공(210)을 통해 충진되며, 이 충진공은 제1도에 도시한 바와 같이 지지판(110)을 통해 잉크 저장기(150)까지 관통된 구멍으로 되어 있다. 잉크 저장기(150)은 우선 충진공(210)에 부분적인 진공을 형성하여 잉크 저장기(150)내에 있는 대부분의 공기를 제거한 후에, 이 부분적인 진공력에 의해 액체 잉크가 잉크 저장기(150)내로 흡입되게 한다. 다음에 충진공(210)을 밀봉 폐쇄하여, 분사 저항기(20)이 가동될 때 낙하 배출공(90)을 통한 배출 이외에는 잉크가 저장기(150)으로부터 배출되지 못하게 한다. 따라서, 전체적인 잉크 분사 헤드를 통한 잉크의 통로는 소형 낙하 배출공(90)을 제외하고는 유압적으로 밀봉된다.The ink reservoir 150 is filled through the filling hole 210, and the filling hole is a hole that penetrates through the support plate 110 to the ink reservoir 150 as shown in FIG. 1. The ink reservoir 150 first forms a partial vacuum in the filling hole 210 to remove most of the air in the ink reservoir 150, and then, by this partial vacuum force, the liquid ink is stored in the ink reservoir 150. Inhalation into The filling hole 210 is then hermetically closed to prevent ink from being discharged from the reservoir 150 except for discharge through the drop discharge hole 90 when the injection resistor 20 is activated. Thus, the passage of ink through the entire ink ejection head is hydraulically sealed except for the small drop ejection hole 90.

사용시에는, 헤드를 정렬핀(120)을 사용하여 인쇄기에 정렬시키고, 고정 장치(도시 안됨)를 사용하여 지지판(110) 또는 외부 하우징(190)에 고정시킨다. 인쇄기는 전기 접점(도시 안됨)을 포함하는데, 이는 패드(40)과 합치되도록 배치되어 분사 저항기(20)을 작동시키기 위해 필요한 전기 신호를 제공한다. 따라서, 헤드가 자체 내장된 잉크를 공급하는 단일체의 유압적으로 밀봉된 장치로 되어 있기 때문에, 사용자는 잉크를 완전히 사용한 후에 액체 연결 장치를 분리 또는 연결시킬 필요가 없게 된다. 잉크를 완전히 소비한 후에는, 헤드 전체를 폐기시키고 새로운 헤드를 장착한다.In use, the head is aligned with the printer using the alignment pins 120 and secured to the support plate 110 or the outer housing 190 using a fixing device (not shown). The printer includes an electrical contact (not shown), which is arranged to mate with pad 40 to provide the electrical signals needed to actuate injection resistor 20. Thus, since the head is a monolithic hydraulically sealed device for supplying self-embedded ink, the user does not need to disconnect or connect the liquid connecting device after the ink is used up. After the ink has been completely consumed, the entire head is discarded and a new head is fitted.
